PLASMA withdrawal skips challenge period

I recently did a plasma withdrawal by mistake because I wanted to transfer matic tokens to ETH,
Apparently MATIC withdrawals default to PLASMA in my polygon wallet. Anyway, what happened was:

  • the challenge period was reached within a minute,
  • the wallet asked me to pay for a second time to continue
  • my tokens are now visible in my ETH wallet
  • the transaction says it’s still pending with a status of ‘Process Exits’

what happened here? should I be concerned?
